MS4800FS Segment Reduction Restart Procedure

!WARNING Do not remove cascaded segments from your installation without making sure

that the accessible areas are protected by other measures. Failure to do so

may result in serious injury.

When you reduce the number of cascaded segments you cause a flex bus

fault. The MS4800FS will enter a fault condition, indicated by error code "95"

on the indicators in the bottom part of the device. This fault code indicates that

there was a reduction in the number of cascaded segments. If the number of

segments is reduced while power is off, the light curtain will power on with

fault code "100".

There is one possibility to clear this fault and restore operation on the reduced

size MS4800FS. The start switch needs to be pressed while the power is

applied. The three indicator LEDs (red, yellow, amber) will flash for approxi-

mately three seconds. The start switch must be released while the LEDs are

flashing to clear fault code "100". Since the MS4800FS has a configurable

start input, care must be taken to ensure that the correct contact configuration

is used and that it is wired properly.

The transmitter will not fault if the number of segments is reduced. However,

to operate normally the transmitter must always match the receiver in the

number of segments and beams.
